SPECIFICATION forming part of Letters Patent No. 597,609, dated January18, 1898.

Application filed June 9, 1897- Serial No. 6%,022. (No model.)

To aZZ whom it may concern:

Be it known that I, HORIS G. FRANCIS, a citizen of the United States,residing at Dexter, in the county of Stoddard and State of Missouri,have invented a new and useful Pea-Huller, of which the following is aspecification.

Thisinvent-ion relates to pea or been hullers, its object being toimprove the construction of machines of this character whereby they willbe rendered more efficient in operation.

With this and other objects in view the invention consists of theseveral details of construction and combinations of parts, as will behereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective View of a pea-huller made inaccordance with my invention. Fig. 2 is a vertical longitudinal section.Fig. 3 is a vertical transverse section. Fig. 4 is a rear end view.

Similar reference-numerals indicate similar parts in the severalfigures.

1 indicates the main casin g of the machine, which may be of any desiredlengthand width and be supported upon wheels 2 in the ordinary manner.

3 indicates a casing projecting upwardly at the front end of the maincasing and communicating therewith, and within this casing is securedthe concave 4, and the cylinder 5 also works within this casing. Theshaft 6 of the cylinder constitutesthe main driving-shaft and issupported in suitable hearings on the frame of the machine. This shaftprojects at each end beyond the sides of the casing 1 and is provided atone end with a belt-pulley '7, from which a drive-belt 8 leads to asuitable source of power. (Not shown.) The cylinder is provided withaseries of round pins 9,which cooperate with similar pins 10 on theconcave to hull the peas or beans. At the upper end of the concave are aseries of knives 11, projecting inwardly toward the cylinder, andbetween which the pins on the cylinder are adapted to work. The objectof providing these knives is to out the vines into short pieces as theyare fed into the machine and thereby greatly facilitate the threshingout of the peas or beans with the expenditure of much less power thanwould be required if the vines were fed in full length.

12 indicates a vibrating screen which inclines upwardly from the frontto the rear of the machine, and the perforations 13 of this screen areof sulhcient size to permit the peas or beans to pass freely throughthem. The screen is supported at each end upon rollers 14, which arejournaled in suitablebearings in the frame of the machine, and thescreen ismoved longitudinally to and fro on these rollers in a manner tobe hereinafter de scribed.

15 indicates an endless belt which is supported on rollers 16 and 17,the former being at the front end of the machine and the latter at itsrear end. The shaft 18 of the roller 16 is provided with pulley 19outside of the casing, and the shaft 6 is provided with a pulley 20 inalinement with the pulley 19, and a belt 21 transmits movement from thepulley 20 to the pulley 19 and thereby drives the endlessbelt 15. Thebelt may be of canvas or any other suitable material and is ofsubstantially the same width as the vibrating screen 12. A series ofcross-bars 22 are secured to the belt, and each bar is provided with aseries of teeth 23, which are adapted to work in contact with the upperface of the screen 12 and are for the purpose of carrying off vines andhulls to discharge them from the rear end of the machine and also to aidthe peas or beans to pass through the perforations in the screen. Thefront end of the belt is directly below the concave, and the vines,hulls, and peas are discharged from the concave onto the belt, which inturn transfers them to the screen and moves them up the incline untilthe peas are separated from the hulls and vines, which latter are thendischarged at the rear end of the machine.

24 indicates a shaft which is journaled in suitable bearings at the rearend of the machine and projects outwardly at one end beyond the casing,where it is provided with a pulley 25. The inner end of the shaftcarries a crank-wheel 26, and a rod 27 connects the crank on the wheelto the vibrating screen 12. The shaft 18 is provided with a pulley 28,and

, from. this pulley a belt 29 leads to the pulley rear end of themachine.

and thereby transmits motion to the shaft 24 and crank-wheel 25, whichresults ingiving the screen a reciprocating movement endwise on itssupportingrollers 14.

indicates a fan at the front end of the machine, the shaft 31 of whichis journaled in suitable bearings in the casing 1. The shaft 31 projectsat one end beyond the casing and is provided with. a pulley 32, which isin alinement with a pulley 33 on the shaft 6, and a belt34= connectsthese two pulleys and therebytransmits motion from thedriveshaft 6 tothe fan. This fan is so arranged as to drive a current of air throughthe peas, hulls, and vines, 850., as they fall from the concave onto thebelt, and thereby carries the lighter rubbish and dust out through thevided with a suitable fiy-wheel 35 in the usual manner.

The screenl2 is secured to the upper face i of the side rails 36, and anilnperforate plate '37 is secured to. the lower surfaces of the saidrails, to be substantially parallel with the screen, and the peas orbeans which pass through the perforations in the screen fallon the plate37 and roll down into the trough 38, which extends transversely of themachine, and from this trough they may be discharged into any suitablereceptacle. A suitable hopper 39 may be arranged over the cylinder andconcave to receive the vines, from which they may be gradually fed intothe concave to be threshed.

In operation the vines as they are received from the field will be fedinto the concave and be forced between the knives 11 by the pins 9 onthe cylinder and cut into short lengths, after which the pins on theconcave and cylinder will cooperate to thresh out the peas, and thepeas, bulls, and short vines will be discharged from the concave ontothe endless belt 15 and then carried up the vibrating screen 12, andduring their movement up the screen the peas will pass through theperforations and the hulls and vines -will be discharged out at the rearend of the machine.

It will be understood that changes in the form, proportion, and theminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is The shaft 6 isprostantially as and for the purpose specified.

' 2. In a pea-hulle'r, the combination with a screen supported in theframe and inclined upwardly from the front to the rear endof themachine,means to reciprocate said screen endwise, an endless belt mounted totravel parallel to the screen with its upper'side moving towardthe frontof the machine, pins projecting from the belt to work overthe surface ofthe screen, a concave and cylinder adapted to thresh out the peas anddischarge the pea vines and hulls onto the upper side of the endlessbelt, and a fan to force acurrent of air through the vines, peas, &c.,as they fall from the concave to the belt,substantially as described. a

In a pea-huller, the combination of a screen supported within theframe and inclined upwardly from the front to therear end of themachine, means to reciprocate said screen endwise, an endless beltmounted to travel parallel to the screen with its upper side movingtoward the front of the machine, pins projecting from the belt to workover the screen, an in clinedplate rigidlyconnected to and arrangedbelow the screen to move with it and receive the peas therefrom, aconcave and cylinder adapted to cut the vines into short lengths, threshout the peas and discharge the peas, vines, &c. onto the upper side ofthe endless belt, and a. fan mounted to revolve in the front of themachine in advance of the front of the belt to force a current ofairthrough the vines, peas, &c., as they fall from the concave to thebelt, substantially as described.
